WINDOW-SASH/ WEIGHT.

vide for the convenient adjustment of the weight. A l This inventionrelates to ,window sash weights comprising an outer metallic shell orcasing and a filling therein; and an object of the invention is toenable said shell or casing .to be substantially of one'piece of metal,

thereby reducing the expense for material and labor in making the sameto a minimum and making the device more substantial.4

The accompanying drawings illustrate the invention. Y f

Figure 1 is a plan of the blank used in forming the shell, showing theadjacent portion of theA blank formed consecutively therewith.

Fig. 2 is a perspective showing the blank bentv up longitudinally, butwith the ends unbent. Fig. 3 is a longitudinal section of the completeweight. Fig. 4l is va transverse section on line X4B X4 in Fig. 3. Fig.5 is asectional View on the line X5 X5 in Fig. 3. Fig. 6 is an invertedplan. Fig. 7 is a plan of a different form of blank adapted forproducing a round-corner tubular weight. Fig. 8 is a' horizontalsectional view through the sashweight formed from the blank shown inFig. 7. j

1 designates a blank or sheet of metal cut or stamped out in such manneras to form the sides and ends of the tubular box-shaped cas'- ing orshell when bent up, as hereinafterde-l scribed. Said blank is bentlongitudinally in square or rectangular shape and by means `of asuitable machine or-by hand, the longitudinal edges of the blank beingoverlapped and bent on one another to form the longitudinal seam orjoint 2. This seam orjoint may be formed either at the corner or in oneside of the square or rectangular shell. The form of blank shown in Fig.1 is adapted to produce a shell in which the seam or joint is formed atone corner, as shown in Fig. 4. At the end corresponding to the upperend of the box-shaped tubular casing theblank'l is formed with two longears 3, preferably tapering outwardly and vSpecification of LettersPatent.

having perforations 4 near their outer ends,

and alternating with said ears 3 said blank is provided with short ears5, which may have notches 6 for the purpose hereinafter set forth. Atthe outer end the blank has two longer ears 7 and two shorter ears 8,alternating vwith one another, the longer ears being preferablyformed-with openings 9. When the blank is bentlongitudinally, as abovedescribed, it will assume theform shown in Fig. 2, and by then bendingover the ears the ends of the tubular boX will be formed in thefollowing manner: At they bottom of the blank the shorter ears 8 arebent inwardly, and the longer ears 7 are then bent inwardly over theshorter ears, the openings 9 thereof coming A suitable packing-plate ofpasteboard or felt cloth or other yielding material (indicated atl 10 inFig. 3) may then be placed against the inner side of these ears to avoidsiftingor leaking, and the shell being then placed on a suitable former,preferably rounded at the end, the parts are pressed together to finalshape and at the` same time the rivet'11 i's clenched, binding the partstogether. The shellmay then be filled withflling material, (indicatedvat 12,) which may be of any suitable nature, preferably of heavyfragmentary material, and the packing 'plate or disk 13 of pasteboard orother puncturable material 'is placed on top of the filling material,the upper ears 5 being then bent down thereover and the longer ears 3being bent inwardly to overlap one another with their openings 4L inline. One of the openings 4is preferably formed in the blank 1 andsmaller than the other opening, so it can be vexpanded to form aneyelet, (indicated at 144 in Fig. 3,) which is clenched or upset overthe other ear to bind the parts together, and the two ears 3 thusforminga bail extending from one side of the shell to the other. 15indicates a suspending rope or cord, which is passed through this,eyelet and knotted beneath the same.

The notches 6 above referred to, when brought opposite one another forman opening giving access to the pasteboard plate or disk 13, the latterbeing puncturable by means of a suitable tool, such as a screw-driver,to let out the desired amount of filling material in case thezweightisfound too heavy. As a safeguard a closure 16 maybe provided, pivoted at17 to one of the ears 5 to swing over the opening formed by the notches6 to close the same. If desired, the packing-plate 13 IIO may beomitted, the closure 16 being alone relied upon to retain the filling.

In case it is desired t0 have the seam at the side instead of at acorner of the tubular box-shaped casing, the side seam being generallythe preferred form, the shell or blank mayT be formed as shown at 21 inFig. 7, and in that case perforations (indicated at 29) may be providedin the longer lugs or ears 27 at the bottom of the blank, so that whenthe longitudinal edges oi' the blank are overlapped and clenched on oneanother these perforations 29 will come in line to enable them toreceive the fastening-rivet. In this case also it is possible to makethe corners of the tubular shell more or less rounded, if desired, andfor this purpose the ears 23, 25, 27, and 28 at the top and bottom ofthe blank may be cut in or notched at their inner ends, as shown at 31,and slotted, as at 32, so as to allow the blank to be bent gradually orin a rounded shape at the corners. These insets also facilitate thebending over of the ears along a definite line. Asimilar purpose may beeffected in the form of blank shown in Fig. 1 by scribing or scoring theblank along lines indicated at 30 30. The bail-ears 27 may beswelled attheir bases, as shown at 33, to serve as guards to prevent the weightfrom catching.

What I claim is 1. Asash-weight comprisingasheet of metal bent to form atubular shell and with its ends inbent to form closures for the ends ofthe shell, the inbent upper ends of the shell also formingrope-attaching means, and filling of fragmentary material in said shell.

2. A sash-weight comprising a shell formed of asheet of metal .bent intubular shape with ears at its lower end bent over one another and thensecured together to form the bottom of the shell, and filling in saidshell.

3. A sash-weight comprising a tubular shell formed of a metal sheet,having its edges secured together by a longitudinal joint and havingears at the lower end turned in to close said end, a packing-plate onthe inside of said lower end, and filling in the shell above thepacking-plate.

4. A sash-weight comprising a tubular metal shell closed at the bottom,said shell having parts at the top bent to extend in proximity to oneanother and formed with perforations to receive and support the cord.

5. A sash-weight comprising a tubular metal shell closed at the bottom,said shell having ears at the top bent over and overlapping one anotherand formed with perforations to receive the supporting-cord, and eyeletmeans at said perfor-ations securing the ears together.

6. A sash-weight comprising a tubular metal shell closed at the bottomand having an opening in its top, a movable closure pivoted to the topfor closing said opening, and filling in said shell.

In testimony whereof I have hereunto set my hand, at Los Angeles,California, this25th day of November, 1904.
